BACKGROUND OF THE RELATED ART

Use of robotic technologies presents a number of advantages over traditional, manual surgery procedures. In addition to other advantages, robotic surgeries often allow for greater precision, control, and access. Despite these advantages, however, the pre-existing robotics platforms have built-in limitations that are tied to their structural designs and underpinnings. In the absence of a truly flexible system, hospitals and health care practitioners are forced to acquire a variety of robotic systems in order to robotically perform a variety of procedures. The high capital costs, combined with the relatively specialization of the systems, have slowed adoption of robotics platforms for surgery.

Accordingly, there is a need for a robotics platform that is configurable for a number of procedures.

DETAILED DESCRIPTION OF THE DRAWINGS

Although certain preferred embodiments and examples are disclosed below, inventive subject matter extends beyond the specifically disclosed embodiments to other alternative embodiments and/or uses, and to modifications and equivalents thereof. Thus, the scope of the claims appended hereto is not limited by any of the particular embodiments described below. For example, in any method or process disclosed herein, the acts or operations of the method or process may be performed in any suitable sequence and are not necessarily limited to any particular disclosed sequence. Various operations may be described as multiple discrete operations in turn, in a manner that may be helpful in understanding certain embodiments; however, the order of description should not be construed to imply that these operations are order dependent. Additionally, the structures, systems, and/or devices described herein may be embodied as integrated components or as separate components.

In clinical applications, the design of the base of the robotics platform often constrains the types of procedures that may be performed by the system. For example, in a system where robotic appendages are only available around the abdomen, urology procedures are precluded from being performed. Likewise, robotic arms below the abdomen may not be useful for laparoscopic procedures. Accordingly, the present invention provides a flexible design such that robotic arms may be delivered to multiple access points in a patient around a surgical bed.

FIG. 1 illustrates a surgical bed with an oval track for robotic arms along the edge of the bed, consistent with an embodiment of the present invention. As shown in the isometric view 100 of the robotic system 101, the system 101 comprises of a surgical bed 102, a rail 103 for mechanical arms 104, a support stand 105, and a system base 106. The surgical bed allows for a hinge 107 such that a portion 108 of surgical bed 102 may be declined at a different angle from the rest of the bed. This may be desirable for certain operations, such as when performing a procedure that requires access a patient's lower abdomen, such as ureteroscopy or hysteroscopy.

Encircling the surgical bed 102, the rail 103 provides a structure to slidingly translate the mechanical arms 104 to a desired location around the surgical bed 102. The rail 103, which may be referred to as a “track”, and the mechanical arms 104 may be slidingly translated along it in order to facilitate access for the arms. The rail 103 also provides allows for the conveyance and reception of power, controls, fluidics, aspiration to the mechanical arms 104. The rail 103 may be fully circular and surround all sides of the surgical bed 102.

The mechanical arms 104 may be operatively coupled to the rail 103. The mechanical arms may also be robotic. The translation of the mechanical arms 104 may be actuated either manually or robotically. The mechanical arms 104 may be coupled independently to the rail 103 or in groups via a mechanical carriage that may slide around the rail 103. In addition to providing structural support to the mechanical arms 104, the carriage may be used to convey and receive power, controls, fluidics, and aspiration to and from the arms 104 to the rail 103.

In combination or individually, the support stand 105 and the system base 106 may be used to house electronics, fluidics, pneumatics, and aspiration. The electronics may be used from control, localization, navigation of the arms 104. Thus, as a robotically-driven platform, system 101 provides for a comprehensive surgical bed and tool solution that may be used to perform any number of procedures around a patient.

FIG. 2 illustrates a surgical bed with a U-shaped track for robotic arms along the edge of the bed, consistent with an embodiment of the present invention. As shown in the isometric view 200 of the robotic system 201, the system 201 comprises of a surgical bed 202, a rail 203 for mechanical arms 204, a support stand 205, and a system base 206. Like in system 101, the surgical bed 202 allows for a hinge 207 such that a portion 208 of surgical bed 202 may be declined at a different angle from the rest of the bed 202. As discussed earlier, this may be desirable for certain operations, such as when performing a procedure that requires access a patient's lower abdomen, such as ureteroscopy, hysteroscopy, or colonoscopy.

Running along the surgical bed 202, the rail 203 provides a structure to slidingly translate the mechanical arms 204 to a desired location around the surgical bed 202. Unlike rail 103, rail 203 uses a U-shape that enhances access the surgical bed 202. This may provide advantages when position the patient and accessing operative sites on a patient's lower abdomen. The longer leg of the rail 203 allows for the mechanical arms to be aligned to convey a medical instrument into the patient by means of a “virtual rail” such as one discussed in the aforementioned patent applications. As before, the rail 203 may be referred to as a “track”, and the mechanical arms 204 may be slidingly translated along it in order to facilitate access for the arms. The rail 203 also provides allows for the conveyance and reception of power, controls, fluidics, aspiration to the mechanical arms 204.

In combination or individually, the support stand 205 and the system base 206 may be used to house electronics, fluidics, pneumatics, and aspiration. The electronics may be used from control, localization, navigation of the arms 204. Thus, as a robotically-driven platform, system 201 provides for an improved, comprehensive surgical bed and tool solution that may be used to perform any number of procedures around a patient.

As deployed, the mechanical arms 104 from system 101 and mechanical arms 204 and system 201 are positioned to perform endolumenal procedures to access the access points in the lower abdomen (e.g., urology, ureteroscopy, hysteroscopy, or colonoscopy) and upper abdomen (e.g., bronchoscopy, gastro-intestinal).

As shown in isometric view 300, system 301 incorporates all the technologies disclosed with respect to system 201 with the additional vertical translation apparatus 302 that enables control over the vertical height of the rail 303. System 301 thus allows for vertical translation of the rail 303 relative to the support stand 304.

FIG. 4 illustrates a surgical bed with a rounded track for robotic arms along the edge of the bed, consistent with an embodiment of the present invention. As shown in the isometric view 400 of the robotic system 401, the system 401 comprises of a surgical bed 402, a rail 403 (or “track”) for mechanical arms 404, a support stand 405, and a system base 406. The surgical bed 402 may be configured to translate horizontally to position patient 407 relative to mechanical arms 404.

Encircling the surgical bed 402, the rail 403 provides a structure to slidingly translate the mechanical arms 404 to a desired location around the surgical bed 402. The rail 403, which may be referred to as a “track”, and the mechanical arms 404 may be slidingly translated along it in order to facilitate access for the arms. The rail 403 also provides allows for the conveyance and reception of power, controls, fluidics, aspiration to the mechanical arms 404.

The mechanical arms 404 may be operatively coupled to the rail 403. The mechanical arms 404 may also be robotic. The translation of the mechanical arms 404 may be actuated either manually or robotically. The mechanical arms 404 may be coupled independently to the rail 403 or in groups via a mechanical carriage that may slide around the rail 403. In addition to providing structural support to the mechanical arms 404, the carriage may be used to convey and receive power, controls, fluidics, and aspiration to and from the arms 404 to the rail 403. The ability to translate the arms 404 and translate the bed 402 allows for nearly unlimited access to different portions of the anatomy of patient 407.

In combination or individually, the support stand 405 and the system base 406 may be used to house electronics, fluidics, pneumatics, and aspiration. The electronics may be used from control, localization, navigation of the arms 404. Thus, as a robotically-driven platform, system 401 provides for a comprehensive surgical bed and tool solution that may be used to perform any number of procedures around a patient. The support stand 405 may also translate vertically, allowing for easier access to the patient 407 and operative site.

As deployed in view 400, mechanical arms 404 may be positioned to access the abdomen of patient 407 for laparoscopic procedures.

The electronics may be used from control, localization, navigation of the arms 504, 505, 506. Thus, as a robotically-driven platform, system 501 provides for a comprehensive surgical bed and tool solution that may be used to perform any number of procedures around a patient.
